Thank you Amanda for the information. I will look at it later today. I have looked at the Mayo Clinic site and watched a video of a doctor describing the procedure and all that goes into it. It did not show an actual procedure, though. I would love to come to Mayo for this, but, am nervous of managing by myself. I do want to reach out to someone at Mayo after I get a follow up here. How do I choose the best EP for Atrial Tachycardia rising from the crista terminalis, which I am told needs an Epicardial ablation? I want to choose the EP with the most experience and successful outcomes. Is that something that would be chosen for me?
